TL;DR: In this article, a new methodology for the generation of thermal response factors of geothermal bore fields using the concept of g-functions introduced by Eskilson was introduced, where boreholes are divided into segments to consider the variation of the heat extraction rates along the length of the boreholes and the analytical finite line source (FLS) solution is used to calculate the temperature variations at the wall of each borehole segment along the axial direction.

TL;DR: In this article, the authors examined the thermal response of bore fields using the concept of g-functions introduced by Eskilson and proposed a new method to approximate the g-function.

TL;DR: In this paper, a model to calculate g-functions accounting for the axial variation of borehole wall temperatures and heat extraction rates due to thermal interaction between the fluid and the borehole walls is presented.

TL;DR: In this paper, a simulation model is developed to evaluate the performance of shallow solar assisted ground heat exchanger bore fields, which comprises several relatively shallow vertical boreholes with independent circuits connected to both a ground source heat pump and solar collectors.

TL;DR: In this article, an experimental setup was built to obtain the experimental g -function of a small-scale borehole, which is calculated from the measured borehole wall temperature and the net heat injection rate into a 400mm long borehole inserted in a 2m 3 sand tank with known thermal properties.
